Processing details
■Operation processing
• These functions convert the INT type data input to (s) to BOOL type data and output from (d).
• When the input value is 0, these functions output "FALSE".
• When the input value is any value other than 0, these functions output "TRUE".
(s)
0

INT
• A value input to (s) is the INT type data value.
■Operation result
1.
Function without EN/ENO
The operation processing is executed. The operation output value is output from (d).
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
Execution condition
EN
TRUE (Executes operation)
FALSE (Stops operation)
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
Operation error
There is no operation error.
